so, it's probably and upgrade from what you have, but not the newest model, it says it will charge battery
, but does not say if it has smart charge capability.
if the one you have works, it might not be worth the effort.
I changed the guts of mine so that I had a new smart charging converter, but the old breaker box so I didn't have to fool with as much wiring. I installed a PD9145 converter in the space my old converters transformer section was mounted in
everybody has an opinion, you need to do what works for you
